Totally understand when the runway marking helps identify the location of an aircraft.. and I believe the only marking that would help is the runway number. Why would I need to know what a yellow demarkation bar is?I hear you, but I had a few questions pertaining to markings and signage on runways, and also what the runway numbers mean in relation to direction, and which runway based to land on if wind was in X direction
questions on terminology of aircraft position in a landing pattern (base, left, midfield, final) etc. and how to identify is the aircraft is east/west north of your position based on these call outs.
I worked extra hard on these general areas and I ended up seeing quite a bit of questions on them
